STOVE PLAT'FORlVl.

SPECIFICATION forming part of Letters Patent No. 312,933, dated February24, 1885.

Application [ilcd January 523, 1883.

To all whom it may concern:

Be it known that I, ISAAC VAN I-LienN, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Stove-Platforms, of which the following isaspecification, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

I11 my Patent No. 271,163, granted January 23, 1883, the object is toproduce a diskshaped cover inclosing all parts of the periphery of thebase, the disk being formed or shaped without the spinning process,which is impracticable with crystallized tin, because of its hardnessand'stiffness.

My present invention is directed to a square or rectangular platformhaving separate c rnerpieces, and also contemplates the use ofcrystallized tin, the advantages of which over zinc and othersubstances, by reason of its greater durability and attractiveness inappearance, are apparent.

In the accompanying drawings, Figure 1 is a plan view of .a sheet-n1etalblank illustrating the mode of manufacturing and constructing myimproved cover. Fig. 2 is a perspective view showing the cover whenapplied to the board or base, but without the cornerpieces. Fig. 3 is aperspective view of one of the corner-pieces. Fig. 4 is a perspectiveview of the entire platform complete with the corner-pieces attached.

Similar letters'of reference indicate similar parts in the respectivefigures.

In constructing my improved cover, I take a sheet of tin, and byapprovedmachinery stamp or cut out the corners by one or successiveoperations. A blank thus formed is shown in Fig. l. The next step is tocrystallize the surface of the tin. I next bend over the sides, so as toform double angles, as represented in Fig. 2, the lower portions, a,being parallel with the surface of the blank. The board or base I) isnow sprung or inserted within the bent sides of the cover, and the baseand blank are securely pressed or forced together.

The eornerpiece 0 (shown enlarged in Fi 3) is madeof a sheet of tinstamped out to the proper shape and bent to angles, as shown, whereby aclamp is formed to fit over the corners of the blank and base. Thecorner-pieces (No model.)

are attached to the base by tacks or other means. Heretofore in thetrade corner-pieces have been formed and bent to embrace the corners ofa stove-board; but the objection to them has been that they have beeninsufficient to sustain rough usage or to receive blows with outbecoming indented or bruised on their edges or perpendicular sides. Thecornerpiece which I employ is strengthened by having its outer edgescorrugated, as shown in the drawings.

I am aware that it is not new to increase the strength of metallicarticles by corrugating them, as this has been extensively done in thevarious arts; but I am not aware that the strength of the corner-piecesof a stoveplatform has been enhanced in this manner. An advantageadditional to that of increased strength is found in the fact that thecorru' gated surface adds greatly to the attractiveness of the platformby serving as a. reflector, after the manner of reflectors for lamps,long in common use.

I am aware of Patent No. 233,947, granted November 2, 1880, to H.Rendtorff, and disclaim the invention therein described. Said patentshows a stove-board cover made in sections of crystallized tin andprovided with corner-pieces of apeculiar form, and differs both in theconstruction of the cover and corner pieces from the invention hereindescribed. The cover, being in sections, requires to be attachedtogether, which increases its cost without in any degree adding to itsstrength, appearance, or utility. I also disclaim the inventiondescribed in Patent No. 124,237, granted March 5, 1872, to IV. Vestlake.

The crystallized tin may be variously colored and afterward varnished.The cornerpieces have preferably a bright surface, produced bynickel-plating, silverplating, or by other means, and when employed withthe crystallized cover form a pleasing contrast.

While I preferably use corner-pieces having outer corrugated surfaces,it is within the scope of my invention to use with the one sheet-boardcorner-pieces having plain outer surfaces.

I claim as my invention- In a stove-platform, a base of suitable111aterial, and a top composed of 21 sheet of crysmy hand and affixed myseal this 23d day of tallized tin having its corners removed andJanuary, 1883. its remainin ed es turned in the shat 3e of a w doubleright? angle over and upon th edges ISAAC VAN G 5 and vertical sides ofthe base, combined with Witnesses:

corner-pieces, substantially as set forth. GEORGE H. HOWARD,

In testimony whereof I have hereunto set CHARLES P. WEBSTER.
